The picture is deceptive. The concentrate is original and good, but the picture of the bottle is not accurate and suggests that this concentrate is in some way different from the same product being sold more cheaply on Amazon (see pic below). I thought it may have been the yellow stuff that comes in small sachets with the new Window Vac but is not and so you'd be paying double for the same concentrate if you bought it from this reseller.

Very good results with no smears, Rain doesn't seem to mark the windows after use.. When used with the Karcher Window Vac the windows are sparkling. Do not get this item mixed up with the Karcher universal cleaner which is for the steam cleaners. All round a very good product.

I have over the years tried all types of commercial window cleaning solutions, cloths, brushes etc. usually going back to the old fashioned method - wash with home made solution of vinegar,fairy liquid and water followed by crumpled newspapers to buff the window to a shine, but no more, I have finally found the best window cleaning solution ever which combined with the Karcher Window cleaner makes cleaning windows so easy. I have a problem with my right shoulder and washing inside of windows was always a chore (Window cleaner does outside). I admit to using the Karcher cleaner with my own vinegar solution but didn't feel it got the same results so I have gladly gone back to the Karcher solution. If only they had invented this solution and the Karcher Window cleaner 20 years ago.

I have used in the past many different products to clean windows and glass but never been completely happy with the results. The problem has always been, not so much their cleaning performance but, mainly the traces they leave behind, such as smears.Reluctantly I ordered this Cleaner only because of the good reviews. As soon as I received my 500ml I went into action, anxious to try it. The results were just perfect. Just apply, wipe and buff. No residue or smears and best of all, it leaves the surface with a "polished" look and feel which adds some protection from new dirt. I then went on ant tried this Cleaner on other glass products with the same pleasing results.Stainless Steel is another surface which I despair when I clean. Getting rid of the smears is almost impossible and often takes much, much longer than the "cleaning" it self. With this Window Cleaner my problem has instantly disappeared!

KArcher, thank you and I hope you stick with the same formula in the future and not change it as a lot of manufacturers recently have been doing with disappointing results.

Would I recommend this Cleaner? Of course 100%.

So far so good, I have only used it twice since receiving it but it is a definite improvement on the Fairy liquid mix I used previously . The glass is much clearer than before, and together with the Karcher window vac it does leave the glass with a totally streak free finish.The fact that it is concentrated and has to be diluted to a ratio of 10 to 1 does mean it should last quite a while.Applying it with an old handsprayer (previously contained weed killer) which works perfectly well, then spread the liquid over the glass with a microfibre cloth and finish of with the vac.

Having used the small sachets of the solution and found the product excellent for streak free window cleaning, I realized that this was an expensive method and could save money by buying the 500cc Concentrated Window Cleaner. It is the same solution and works exactly the as before. After purchasing the Karcher system through Amazon, I now find that my wife has lumbered me with cleaning the windows in our household. However, its a breeze compared with the previous method.

The bottle of concentrated window cleaner arrived safe and sound and within the time scale.It is a different designed bottle to the one shown in the picture but contains the same product so is fine.I look forward to using it with my new Karcher window vac.
